To all whom it may concern.-

Be it known that I, OSCAR BRiiNLER, a subject of theEmperor of Germany,and a resident of Eutritzsch-Leipsic, in the Empire of Germany, haveinvented a new and useful Petroleum-Engine, (for which I have obtained apatent in Germany, No. 65,071, bearing date February14, 1892; inSwitzerland, No. 5,052, bearing date April 25, 1892; in France, No.220,696, bearing date April 5, 1892; in Great Britain, No. 7,047,bearing date April 4, 1892; in Belgium, No. 99,487, bearing date April29, 1892; in Sweden, No. 3,907, bearing date May 7,1892; in Italy, No.31,849/443, bearing date May 11, 1892; in Victoria, No. 9,696, bearingdate June 3, 1892; in New South Wales, No. 3,796, bearing date June 7,1892; in New Zealand, No. 5,601, hearing date June 17, 1892; in Spain,No. 13,247, bearing date April 29, 1892,) of which the following is aspecification.

The object of this invention is a contrivance in petroleum motors,represented by the accompanying drawings, in which-- Figure 1 is asection of the respective portion of the cylinder of a petroleum motor.Fig. 2 represents a modified arrangement.

This device has for its purpose to utilize the air-current, which isdrawn by suction throttle valve 0 a greater or smaller portion of thedrawn in air-current will pass into tube at, through the curved end ofwhich it arrives in the evaporator g located belowthe throttle valve 0and terminates in the charge space a of the cylinder. At the curved endof the tube (1 is provided the inlet e for the petroleum. The aircurrent passing through tube at meets petroleum, supplied through tube 6and having accumulated in the cavity fof tube din front of theevaporator, and carries this petroleum-with it. The throttle valve 6being located above the opening of the evaporator, no difiused petroleumis blown against said valve.

In the modified construction shown by Fig. 2 the curved'tube (1 servesat the same time as an evaporator. The channel e through which thepetroleum is supplied is disposed in a short tube d connecting the upperend of the tube (1 to the cylinder. This tube d is provided with anozzle 1' and with a block it doflecting the air current to the cavityf.

What I claim is\- 1. In a gas-engine, the combination of the cylinder;an air passage and air-inlet valve 6 in said cylinder; 2. throttle-valvec in said passage; a curved tube 01 entering said passage to one side ofsaid throttle-valve, and
